As you know, your in-game account can be synced with your forum account by typing /syncaccount in-game.
But now, you can also sync your forum account to your Discord account on the Candycraft Discord.

Dylan has kindly created a GIF explaining exactly how to sync your forum account to your Discord account:

Over on Discord, we've now got separate text channels for each exclusive rank.
When your account is synced, your profile will have your rank displayed, and you will have access to the channels for and below your rank!
